Definitions

  • the present invention relates to a baby carriage comprising a seat hammock and more particularly, it relates to a baby carriage having a core in each of a seat part and a backrest part of the seat hammock.
  • Japanese Unexamined Utility Model Publication No. 7-4248 discloses a lightweight type of baby carriage in which a seat hammock is mounted on a body frame.
  • the baby carriage disclosed in the above document is folded so as to shrink in the width direction.
  • a backrest sheet part of the hammock is supported by a belt member from behind and a reclined angle of the backrest sheet part can be varied by adjusting a length of the belt.
  • a reclining structure of the backrest part is very simple and its weight can be reduced.
  • the seat hammock has a core in each of a seating surface sheet part and the backrest sheet part.
  • a seating surface core and a back surface core are separated so as not to hinder a folding operation.
  • width dimensions of the seating surface core and the back surface core are considerably reduced so that the body frame can easily shrink in the width direction.
  • the respective seating surface core and back surface core are constituted so as to be bent in the shape of wedge in the width direction so that the seating surface core and the back surface core can reduce their width dimensions together with the body frame.
  • the backrest sheet part is connected to the seating surface sheet part by a cloth of the hammock only.
  • the backrest sheet part is swayed from side to side by oscillations generated in accordance with movements of the baby carriage. Because of such lateral sway of the backrest sheet part, the child feels uncomfortable and a parent feels uneasy.
  • a baby carriage folded so as to be reduced in dimension in the width direction comprises a body frame and a seat hammock.
  • the body frame includes a seating surface supporting member, and a pair of side vertical frame members extending to rise upward from both sides of a rear end region of the seating surface supporting member.
  • the seat hammock includes a seating surface sheet part extending over the seating surface supporting member, and a backrest sheet part connected to a rear edge of the seating surface sheet part and extending between the pair of side vertical frame members.
  • the seating surface sheet part includes a seating surface core
  • the backrest sheet part includes a back surface core.
  • the seating surface core and the back surface core are constituted by a core continuously extending from the seating surface sheet part to the backrest sheet part.
  • the back surface core and the seating surface core are formed of the continuous core, the lateral sway of the backrest sheet part including the back surface core can be prevented as much as possible.
  • the back surface core preferably ranges over the whole width dimension of the backrest sheet part.
  • the back surface core is a sheet of plate-shaped member extending over the whole length of the backrest sheet part in the width direction, for example.
  • the width dimension of the back surface core is larger than a distance between the pair of side vertical frame members in a folded state of the baby carriage, and the backrest sheet part including the back surface core is positioned behind the pair of side vertical frame members in the folded state of the baby carriage.
  • the back surface core has a tapered configuration in which the width is increased toward the upper side.
  • the seating surface core and the back surface core are preferably a sheet of flat plate having a concave portion at a bending point thereof.
  • the concave portion is a notch formed in a back surface of the flat plate.
  • the part at the bending point may be thinned instead of being notched.
  • the concave portions are provided at a plurality of positions at intervals in the longitudinal direction of the core in order to connect the seating surface core and the back surface core to be smoothly curved.
  • the buttocks of the child can be stably supported in a large space.
  • the core includes a hard resin plate and a cushion attached thereon.
  • a hinge for connecting the seating surface core and the back surface core to be bent is formed by a thinned part of the resin plate constituting the concave portion.
  • the baby carriage has a structure in which the backrest sheet part is supported from behind by a string member, for example.
  • the back surface string member extends over the whole length of the back surface of the backrest sheet part in the width direction and has both ends connected to the pair of side vertical frame members.
  • the backrest sheet part includes a head part core connected to an upper edge of the back surface core.
  • the head part core is preferably connected to the back surface core so as to be allowed to be bent.
  • the head part core and the back surface core may be constituted by a sheet of plate. Alternatively, they may be formed of different members and connected by a hinge.
  • An illustrated baby carriage 1 can take the form of a chair shown in Figs. 1 to 3 and the form of a bed shown in Fig. 4 in a used state.
  • the baby carriage 1 is reduced in dimension in the width direction and stands by itself in a folded state. Since a mechanism for folding the baby carriage by reducing a dimension in the width direction is well known in this field, detailed illustration and description thereof are omitted.
  • the baby carriage 1 comprises a body frame 10 constituting a body and a seat hammock 20 mounted thereon.
  • the body frame 10 includes a seating surface supporting member 11 supporting a seating surface, and a pair of side vertical frame members 12 extending to rise upward from both sides of a rear end of the seating surface supporting member 11. Upper ends of the pair of side vertical frame members 12 are connected by an inverted U-shaped connection member 13.
  • the pair of side vertical frame members 12 and the inverted U-shaped connection member 13 constitute a push bar for moving the baby carriage.
  • the seat hammock 20 includes a seating surface sheet part 21 extending over the seating surface supporting member 11 of the body frame, a backrest sheet part 22 connected to a rear edge of the seating surface sheet part 21 and a pair of side surface sheet parts 23 rising from both side edges of the backrest sheet part 22 and protruding forward.
  • a core 50 in the form of a sheet of flat plate shown in Fig. 10 is contained in the backrest sheet part 22 and the seating surface sheet part 21 of the seat hammock 20.
  • the core 50 includes a hard resin plate 55 and a cushion 54 attached thereon.
  • the core 50 is divided into three regions, that is, a head part core 51, a back surface core 52 and a seating surface core 53.
  • the head part core 51 and the back surface core 52 are connected to be allowed to be bent by a notch 56 provided in the resin plate 55 on the back surface side.
  • a hinge for connecting them to be bent is formed of a thinned part of the resin plate 55 formed by being notched.
  • the head part core 51 rises from the back surface core 52. From this state, when the head part core 51 is turned clockwise to be in the same plane with the back surface core 52, since an end face of the resin plate of the head part core 51 abuts on an end face of the resin plate of the back surface core 52, the same plane state of them is stably maintained.
  • the back surface core 52 and the seating surface core 53 are connected to be smoothly bent by three notches 57 provided in the resin plate 55 on the back surface side. Hinges for connecting them to be bent are formed by thinned parts of the resin plate 55 formed by being notched. Since three notches 57 are provided, the back surface core 52 and the seating surface core 53 can be connected so as to be smoothly curved. As a result, buttocks of a child seated can be stably supported in a large space.
  • the back surface core 52 and the head part core 51 are tapered so as to become wide toward the upper side.
  • the maximum width dimensions of the back surface core 52 and the head part core 51 preferably range over the whole width dimension of the backrest sheet part 22.
  • the back surface core 52 and the head part core 51 are made to have the wide width dimensions and the seating surface core 53 and the back surface core 52 are constituted by a sheet of core, even in the illustrated lightweight type of baby carriage 1, the posture of the backrest sheet part 22 can be stably maintained.
  • the seating surface core and the back surface core are separated and width dimension of the core is further reduced so that the folding operation may not be hindered.
  • the child is seated in the seat, since the child is held by a crotch belt and a waist belt, a movement of the seating surface sheet part is restrained.
  • the backrest sheet part is connected to the seating surface sheet part by a cloth of the hammock only and a width dimension of the back surface core is small, the backrest sheet part is swayed from side to side by oscillations generated in accordance with movements of the baby carriage.
  • the back surface core 52 and the seating surface core 53 are formed of one common core, the lateral sway of the backrest sheet part 22 can be restrained as much as possible. This effect can be further enhanced when the width dimension of the back surface core 52 is increased and the back surface core 52 ranges over the whole width dimension of the backrest sheet part 22.
  • Fig. 15 shows a used state of the baby carriage 1
  • Fig. 16 shows a folded state of the baby carriage 1.
  • the back surface core 52 ranges over the whole width dimension of the backrest sheet part 22.
  • the backrest sheet part 22 including the back surface core 52 is not bent in the width direction especially, and positioned behind the pair of side vertical frame members 12. In such folded structure, even when the width dimension of the back surface core 52 is increased, the folding operation of the baby carriage shrinking in the width direction is not hindered.
  • the pair of side surface sheet parts 23 includes protection pads 60 at positions corresponding to a height of a head of the child seated.
  • the pair of the side surface sheet parts 23 including the protection pads 60 protrudes forward of the pair of side vertical frame members 12.
  • the side surface sheet parts 23 including the protection pads are positioned backward of the pair of side vertical frame members 12.
  • the baby carriage 1 includes a back surface support 30 connected to the body frame 10 in such a manner that the backrest part 22 can be reclined and supported from behind.
  • the back surface support 30 is described in detail with reference to Figs. 3, 13 and 14.
  • the back surface support 30 includes a back surface string member extending over the whole length of the back surface of the backrest sheet part 22 in the width direction and having both ends connected to the pair of side vertical frames 12.
  • the back surface string member is constituted by right and left belts 31, right and left strings 32 and a lock member 33.
  • the right and left belts 31 each have one end connected to the pair of side vertical frame members 12.
  • a pair of guide sleeves 24 for passing the right and left belts 31 are sewed on the back surface of the backrest sheet part 22 of the hammock.
  • the right and left strings 32 are connected to the other ends of the right and left belts 31 passing through the guide sleeves 24.
  • the right and left strings 32 pass through the lock member 33.
  • the lock member 33 comprises a case 34, a grip 35 movable up and down, a click 36 positioned at an upper end of the grip 35 and a spring 37 forcing the grip 35 to move upward.
  • the right and left belts 31 are forced to be separated.
  • the click 36 and the case 34 of the lock member 33 engage with the right and left strings 32, the right and left strings 32 are prevented from being moved upward.
  • the posture of the backrest sheet part 22 can be stably maintained by the back surface support 30.
  • the grip 35 of the lock member 33 is just pulled down by a finger. Since the engagement of the click 36 with the right and left strings 32 can be released by pulling down the grip 35, the backrest sheet part 22 can be easily reclined. When the backrest sheet part 22 is positioned at a desired angle, the click 36 forced by the spring 37 engages with the right and left strings 32 by releasing the grip 35 from the finger, so that the position of the backrest sheet part 22 can be fixed.
  • an upper end region 25 of the backrest sheet part 22 is bent from the remaining backrest sheet part to protect a top of the head of the child.
  • Such change in form is attained by providing an upper end connection member 40 connecting an upper end of the backrest sheet part 22 to the side vertical frame members 12.
  • the upper end connection member 40 in the form of a band or a strip is provided at the upper end of the seat hammock 20.
  • the upper end connection member 40 passes through a guide sleeve 41 sewed on the upper end of the seat hammock 20.
  • the pair of side surface sheet parts 23 of the seat hammock 20 is wound around the pair of side vertical frame member 12 to be fixed. More specifically, a male button 26 and a female button 27 which are mounted on the side surface sheet part 23 engage with a female button 14 and a male button 15 mounted on the side vertical frame member, respectively.
  • the upper end connection member 40 is in a loose state in which there is no load applied until a reclined angle of the backrest sheet part 22 reaches a predetermined value. Meanwhile, when the reclined angle of the backrest sheet part 22 reaches the predetermined value, the upper end connection member 40 becomes tense and the position of the upper end of the backrest sheet part 22 is fixed. Therefore, when the backrest sheet part 22 is further reclined beyond the predetermined angle, the upper end region 25 of the backrest sheet part 22 is bent from the remaining backrest sheet part so as to have a configuration which covers the top of the head of the child as shown in Fig 4.
  • the illustrated baby carriage 1 has a structure in which the baby carriage can be easily carried in the folded state. This is described with reference to Figs. 6 to 9 and Fig. 13.
  • the baby carriage can be easily carried when the baby carriage 1 in the folded state is held by a suspension belt 2 on a shoulder.
  • the form of holding the baby carriage longitudinally shown in Fig. 7 and the form of holding the baby carriage laterally as shown in Fig. 9 can be appropriately selected.
  • the baby carriage can be held on either right or left shoulder.
  • the baby carriage comprises the suspension belt 2 and four belt connection points for connecting ends of the suspension belt 2. It is preferable that the belt connection points are provided right and left positions in an upper region and right and left positions in a lower region across the center of gravity of the baby carriage in the folded state in order to balance the weight.
  • the belt connection points are preferably provided on the back surface side of the baby carriage so that the suspension belt 2 may not get in the way of the child seated in the seat.
  • set rings 16 are mounted on the pair of side vertical frame members 12.
  • the suspension belt 2 has hooks having the well-known structure, on both ends. As shown in Fig. 6, when the suspension belt 2 is connected to the upper two belt connection points, the folded baby carriage can be longitudinally held as shown in Fig. 7.
  • a set ring 17 is mounted on the rear end of the member supporting the seating surface and the same set ring 17 is provided on the other side (not shown).
  • the suspension belt 2 when the suspension belt 2 is connected to the right upper set ring 16 and the left lower set ring 17, the folded baby carriage can be laterally held as shown in Fig. 9.
